I've started looking at other member's WL when I receive a WL request to see if I have any other WL items that they may have on their WL that I can post directly to them (if they're interested- I would PM them...) to save on postage, if possible. (I'll eventually use the forum listsigs for this too... once I get some series "groups" together for posting...)

I like using DC (for my own peace of mind & the quick credit!).

My question is: If I receive a WL request, then later post something to their WL, will I have to send 2 different packages in order to still use DC, or will the system automatically know they're both going to the same address & list both on the same DC? Or do they both have to be ordered at the same time in order to do this? (Anyone tried it yet?... I haven't because I wasn't sure what the system would do...)

I hope that made sense... any shipping pros out there that can help? Thanks! :)

I've done this before. The system will automatically know that both books are being mailed to the same address and will combine them. You only need to send one package with the one DC number. Hope this helps.
